FILTER.

SPECIFICATION forming 4part of Letters Patent No. 563,639, dated July 7,1896. Application filed May 23,1895. Serial No. 550,417. (No model.)

section 1, and preferably cast or formed integrally therewith, is a diaphragm et, forming a pan 4, the bottom of which is provided nth a plurality of perforations 5, about cach of 5 5 which is cast a boss G. Arranged within the upper end of said section 1, and above the diaphragm 4, are two or more trays 7 and S, which are hinged at one side, as at S), to the section 1, and are provided with laterally- 6o projecting bifurcated lugs 10, through which are adapted to pass bolts 1l, pivotally connected to the upper outer sides of the section l, nuts 12 being tapped over the upper ends To al?, whom tm/ay con-cern.-

Be it known that we, Louis J. BARTHELEMY and Ansrrnn L. BARTHELEMY, citizens of the United States, residing at New Orleans, in the parish of Orleans and State of Louisiana, have invented certain new and useful Improvements in. Filters; and we do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, and to the figures of reference marked thereon.

This invention relates to lters, and is more section taken on the line 2 2 of Fig. 1. Fig. is formed between said filter-bags and trays. 8o 3o 3 is a top plan view. a is a detail per- Within each of the filter-bags 'let is disposed spective view of one of the filter-bags. Fig. a coiled spring 1,by means of which the especially designed for the filtration of saccharine juices and Syrups; and it has for its object to increase the capacity and efficiency of the class of filters described, and also to provide improved means for cleaning the filter-cloths without opening the filter.

To these ends our invention consists in the novel features and in the construction or arrangement of parts hereinafter described, and pointed out in the claims following the description, duc reference being had to the accompanying drawings, forming a part of this specification, in which- Figure l is an elevation, partly in section, of our improved filter. Fig. 2 is a vertical 5 is a similar view of one of the coiled springs for distending the lter-bags- Fig. 6 is a crosssection of one of the flushing-pipes. Fig. 7 is a perspective view of one of the rubber gaskets employed for effecting a tight joint between the open ends of the filter-bags and the top of the filter.

In order that those skilled in the art may be able to nia-ke and use our invention, we will describe the same in detail, reference being had to the accompanying drawings, in which like numerals of reference indicate corresponding parts.

Referring to said drawings, the numerals 1 and 2 respectively indicate the upper and lower portions of the casing of our improved filter, which at their adjacent edges are provided with flanges 3, by means of which and suitable fastening-bolts the said sections are fastened together. In the upper end of the of said bolts, by means of which the trays are firmly fastened down in place upon the diaphragm fl. The said trays 4 are provided with perforations 13, so arranged that they `will correspond or register with the perforations 5, formed in preferably of a somewhat smaller than said last-named perforations.

diameter Adapted to be secured within each of said perforations 5 are filter-bags 14, formed of any suitable or desired textile material, vthe upper ends of 75 said bags being turned over the bosses G and over rubber gaskets 15, arranged about said bosses, whereby when the trays 7 and S are bolted down in place a perfectly close joint weight of the filtenbags and prevent them 9o from being torn. Should one of said filterbags, however, become torn, or through some cause permit impure juices to escape, a rubber plug may be inserted in the perforation 13 in the tray that communicates with said 95 filter-bag, thus cutting outthe imperfect bag from operation.

Each of thc trays 7 and S is somewhat smaller than one-half the cross-sectional area of the section 1, whereby a space is formed roo/ between the edges of said trays and the sides of the section l,7 for the purpose hereinafter the diaphragm 4, and are discharge-outlet 1S, adapted to 85 made apparent. ln order to facilitate raising and lowering said trays upon their hinges, arms 20 are connected to the hinged sides of the trays, which, at their free ends, carry counterweights 21.

said pipes being closed at one end and atmitsA other end is connected with a steam and Water supply pipe. When steam and water under pressure is admitted to said pipes 22, it is sprayed through the perforations in the pipes in all directions, thoroughly washing 'off` the filter-bags and the interior of the iilter, the water and impurities being carried 0H through the discharge-opening 18 in the hopper-shaped bottom 17, the plug 18a having been rst removed.

From the foregoing description the operation of our improved filter will be readily understood.

The juices to be filtered enter the iilter through an inlet 23, formed in the lower end of the casing 2, land pass through the material forming the filter-bags into the interior thereof, thus freeing the juices of all impurities. The iiltered juices then pass up in the filter-'bags into the trays 7 and 8, from whence they are discharged by suitable outlets 24. Should any of the joints between the filter-bags and the diaphragm and trays prove defective, permitting impure juices to leak therethrough, the said juices will escape into the pan 4, from whence they will be conveyed into a slop-tank (not shown) by a pipe 4b.

XVe have described the filter as being made in two sections 1 and 2, and as having two trays 7 and 8, but it will be evident that the number of said sections and trays may be varied7 the number employed being dependent upon the size of the lter. It will also be evident that the filter may be employed for the iiltration of rliquids of all kinds.

Having described our invention, what we claim is- 1. In a iilter, the combination with a closed casing having an inlet and provided with a perforated top, of a series of filter-bags having open upper ends secured within the perforations in said top, and a tray resting upon the said top and provided with apertures communicating with the open ends of said filterbags, substantially as described.

2. In a filter, the combination with a closed casing having an inlet and provided with a perforated trough-shaped top, of a series of lter-bags having open, upper ends secured within the perforations in said top, a tray seated Within said trough-shaped top and' provided Witli perforations registering with the perforations in the said top, and an outlet for the trough-shaped top, substantially as described.

3. In a filter, the combination with a closed casing having an inlet and provided with a perforated trough-shaped top, of filter-bags having upper open ends secured in the perforations in said top, a tray seated in said trough-shaped top and having openings registering with the openings in the top, and outlets forthe said tray and trough-shaped top, substantially as described.

In testimony whereof We have hereunto subscribed our naines in the presence of two witnesses. l
